Description

Starting with SLING-7682, the HTL compiler implements support for iteration control in data-sly-list and data-sly-repeat. However, the generated iteration control conditions always perform computations. For simple cases (e.g. begin and step are undefined), the step control condition should not be calculated and rather defined as a constant.
